    摘要: Disclosed herein is a metal enolate initiator for polymerizing isocyanates and a method for polymerizing isocyanates by anionic polymerization using the same, in which the initiator forms a cluster upon the initiation and protects stability of terminal anions at the end of the chain to cause controlled polymerization, thus preventing depolymerizaton and improving reaction time and efficiency without the use of a separate additive.

    摘要翻译: 本文公开了用于聚合异氰酸酯的金属烯醇化物引发剂和通过使用该异氰酸酯的阴离子聚合使异氰酸酯聚合的方法,其中引发剂在起始时形成簇并保护链端部末端阴离子的稳定性以引起受控聚合, 从而防止解聚和提高反应时间和效率而不使用单独的添加剂。
